Abstract
PURPOSE:To improve efficiency, by winding respective phase exciting coils for every comb tooth of stator core. CONSTITUTION:Exciting coils 1 are wound for every comb tooth of stator core 3. For example, there are 36 comb teeth and U-W phases comprise 12 exciting coils connected in series for U-W phases. Alternate N and S poles of a magnet 2 are arranged circumferentially on the surface of a rotor 6 integrated with a rotor shaft 5 supported rotatably by a bearing 4. An encoder 8 is arranged through a coupling 7 at the opposite side from the output side of the shaft 5. Consequently, cancelling of flux due to overlapped exciting coil 1 does not occur and fluctuation of torque can be suppressed.
